Ductless Mini-Split Services O’Fallon

Follow a half-century of tradition seen around the world, with ductless mini-splits in O’Fallon, MO. You’ve probably seen photos of buildings in many countries, adding efficient cooling where it’s needed for a more comfortable lifestyle. Our Jerry Kelly Heating, Air Conditioning, Plumbing, & Electrical experts can install and service this convenient feature for your home.

Adding cooling capacity and bringing comfort where it’s needed without architectural obstacles is what ductless AC does best. It’s also an excellent solution for older homes needing HVAC system replacement, quickly taking the place of older ductwork and equipment. Since cooling is delivered through small holes in the outside wall, outdated equipment can just remain idle.

Once you find out about ductless from our NATE-certified HVAC team, you’ll see how convenient it is to install and service. It’s an easier solution for home cooling, without complex installation or blocked window spaces!

How Simple Is Ductless AC To Install And Maintain?

Traditional central air brings refrigerant to an evaporator unit in your home from which cool air is distributed to 150 linear feet or so of bulky ductwork, vents, and intakes. It requires powerful air handling and lots of space.

Ductless mini-splits have a similar compressor unit outside, and deliver refrigerant to each room to be cooled, through a small hole in the outside wall. Distribution heads circulate cool air within the room, with advanced controls and options to make each room more breathable as well as comfortable. It’s a simple cooling solution.

Ductless air conditioning excels at providing:
  • Cooling for out of the way spaces
  • Single room cooling and air circulation
  • Additional BTU capacity for cooling building additions
  • Comfort when ductwork doesn’t fit the architecture

Ductless mini-splits deliver cooling to spaces in your home where ductwork isn’t practical, like attics and basements. It’s perfect for home offices and additions, offering separate cooling so you can turn down central air and stay cool where you want to. Each compressor unit typically offers cooling for up to four spaces, offering lots of flexibility for HVAC design.

As an alternative to zoned ductwork, ductless AC provides independent control of each room it serves. Features like motion sensor thermostat, timers, remote control, even HEPA filters are available for each bedroom, studio, workshop, or any other space.
